United States Patent 3,303,795 SUBMERSHBLE PUMP ADAPTER William M. Slaughter, R0. Box A265, Fuquay-Varina, N.C. 27526 Filed Mar. 26, 1965, Ser. No. 442,937 4 Claims. (Cl. 103-202) This invention has to do with a submersible pump adapter, and more particularly, to an adapter for connecting the casing of a submersible pump to an anchoring standpipe which engages the floor of a well.

An object of the present invention is to provide an adapter which lends itseslf to ready attachment to and detachment from the casing of a submersible pump in an end portion of an anchoring standpipe.

Another object of the present invention is to provide an adapter which holds the submersible pump, when attached to the anchoring standpipe, supported upon the floor of a well, in a stable position to thereby eliminate torque damage to the motor, cable, and head pipe.

A further object of the present invention is to provide an adapter which enables the support of a submersible pump in a well at any desired level from the bottom of the 'Well.

A still further object of the present invention is to provide an adapter which is simple in construction, positive in action, and commercially practical.

Other objects and advantages of the present invention will become apparent from the following description taken in conjunction with the accompanying drawing, in which:

FIGURE 1 is a side elevational view of the submersible pump, the anchoring standpipe and the adapter according to the present invention connecting the standpipe to the pump.

FIGURE 2 is a transverse sectional view taken on the line 22 of FIGURE 1.

FIGURE 3 is a longitudinal sectional view taken on the line 33 of FIGURE 1.

FIGURE 4 is a side elevational view of a modified form of the adapter according to the present invention.

FIGURE 5 is a longitudinal sectional view taken through the adapter and anchoring standpipe of FIG- URE 4.

FIGURE 6 is a plan View taken on the line 6-6 of FIGURE 5.

Referring to FIGURE 1, the numeral 11 designates a perforated well casing in which is supported a submersible pump 12 from a head pipe 14 extending to a ground surface, not shown. An adapter, according to the present invention, and indicated generally by the numeral 16, connects the lower end of the casing 18 of the pump 12 to an anchoring standpipe 24 which extends from the adapter and which has its lower end engaging the floor of the well. Guiding discs 22 and 24 are carried by the head pipe 14 and the standpipe 20, respectively, for holding the pump 12 against twisting movement within the well casing 10.

The adapter 16 comprises a base ring 28 which is conformably shaped to extend across and receive the lower end of the casing 18 of the pump 12, the base ring, FIGURES 2 and 3, being provided with fastening element-receiving means or spaced holes 30. As shown in FIGURES 1 to 3, bolts 32 extend through the respective holes 39 and engage the lower end of the casing 18 of the pump 12.

In the form as illustrated in FIGURES 4 and 5, the

fastening element-receiving means embodies a collar 42 which tapers from the ring 28, and the collar 42 is provided with a fastening element-receiving means or hole 44. A set screw 46 extends through the hole 44 and engages the adjacent portion of the casing 18 of the pump 12. g p

The adapter 16 also includes a sleeve 34 which is constructed so as to receive and have detachably secured thereto the upper end portion of the standpipe 20, the sleeve 34 being provided with internal threading 35 which is in threaded engagement with the external threading 38 provided on the upper end portion of the standpipe 213.

The sleeve 34 is disposed axially of and is spaced from the base ring 28, and extending from the sleeve 34 to the ring 28 is an open work cage 4% which merges into the sleeve 34 and the ring 23. Specifically, the cage 40 is shaped to a cup with the bottom of the cup merging into the sleeve 34 and the top of the cupmerging into the ring 28.

The thus described adapter, because of simplicity of construction, lends itself to ready attachment to and detachment from the casing of the submersible pump and the end portion of the standpipe, and When in use, holds the pump in a stable position in the well and thereby eliminates torque damage to the motor, cable and head pipe. Also, this adapter permits the pump to be supported at any desired level from the bottom of the well, and to the recovered in the event of a broken pipe and/ or cable. In addition, this adapter, because of its construction and ruggedness, extends not only the period of use of the submersible pump, but also reduces the cost of its maintenance.

What is claimed is:

1. An adapter for connecting the casing of a submersi= ble pump to an anchoring standpipe comprising a flat lbase ring conformably shaped to extend across and re= ceive the lower end of said casing, a sleeve constructed so as to receive and have detachably secured thereto the upper end of said standpipe, said sleeve being disposed axially of and spaced from said ring, an open work cage extending from said sleeve to said ring and merging into said sleeve and ring, and fastening element-receiving means on said ring for securing the latter to said pump casing.

2. The adapter according to claim 1, wherein said fastening element means embodies a plurality of boltreceiving holes arranged in spaced relation about said ring.

3. The adapter according to claim 1, wherein said fastening element means embodies a collar projecting from said ring, and a bolt-receiving hole extending transversely through said collar.

4. The adapter according to claim 1, wherein said cage is shaped to a cup with the bottom of the cup merging into said sleeve and the top of the cup merging into said ring.
